High resolution and stereoscopic video recording optical disk, the optical disk reproducing apparatus, and an optical disk recording device

Disclosed is a high resolution video signal recorded optical disc and systems for reproducing it, for the purpose of realization of compatibility with the conventional system for reproducing a normal resolution image. The A high-resolution video signal is divided into a main signal and an auxiliary signal by the video separating means, first interleaving block 54 obtained by dividing each of the streams MPEG encoded or more frame group 1 GOP, the second interleave block 55 alternately recorded on the optical disk 1, a high resolution corresponding type reproducing device, obtaining high-resolution images by reproducing both the first and the second interleave blocks. On the other hand, high quality in-unaware of the playback apparatus, only one of the play of the first or second interleave blocks to obtain a normal resolution image. .FIELD 5
